There's nothing like coming home and smelling that fresh, clean scent. This sometimes becomes a difficult task, as we don't always have the time to do a thorough cleaning, and activities such as cooking can impregnate odours into the air.

In this article, we will tell you about the air purifiers that we have reviewed and considered to be the best according to certain characteristics and above all taking into account the relationship between price and quality.




The most important

  • In a world where breathing clean air is becoming more and more difficult, an air purifier can be a great ally and maybe you have never considered it or you still don't know how they work.
  • You can find different purifiers with different designs and particular characteristics, but in the end, their function is the same in all of them, and naturally it is to purify the air of toxic particles and pollution that may be in your home.
  • If you are a person who suffers from asthma, or any other type of respiratory problems caused by allergies, this device could make your life more breathable, as it will clean and purify the air in the room where you are.

What are air purifiers?

Air purifiers are an electronic device that, as the name suggests, purifies the air in a given space, depending on where it is stationed, by removing toxic or malicious particles, such as:

  • Dust
  • Bacteria and germs
  • Mites
  • Pet hair and dander
  • Bad smells caused by tobacco or dampness
  • Food odours

These particles and pollutants are trapped by a HEPA or Hepa (High Profficiency Particular Air) type air filter through a complex network of fibres. We will talk about this in more detail later, as it is one of the main and most important features of these devices. It is important to mention that some air purifiers do not work with this filter but by means of an ioniser and others called ozonators, as they generate and release small amounts of ozone, which we will also talk about later when we compare these types.

What are the advantages of air purifiers?

Air purifiers can be likened to a fan with a sophisticated design and are portable in use as they are simply plugged into an electrical outlet. Originally used almost exclusively for industrial and large-scale use, they are now more popular in the home.

Advantages
  • They can be placed in any place or room in your home as they are portable
  • They greatly improve the reduction of dust and therefore the risk of allergies
  • They eliminate many germs that circulate through the air avoiding contagion and airborne diseases
Disadvantages
  • They require maintenance as the filters must be cleaned periodically in the models that use reusable filters
  • They consume more energy than a normal fan
  • You must replace the filter at least once a year

HEPA air purifiers, ionisers and ozonisers - what should you pay attention to?

When it comes to air cleaning, there are not only air purifiers as such, but we can also find ionisers and ozonisers, although as you may have noticed so far, this article is mainly about air purifiers, as we consider them to be the best option due to their great versatility.

HEPA: Purifiers with HEPA filters can ensure up to almost 100% effectiveness in terms of air cleaning. In air purifiers, up to 3 more filters are usually incorporated such as the pre-filter, the active carbon filter which is the most effective in neutralising and eliminating odours, and also electrostatic filters, but regardless of this, the most important will be the HEPA filter, due to its high percentage of efficiency.

Ionisers: Ionisers are other types of purifiers, but they work in a different way, cleaning the air by emitting negative ions that stick to toxic or polluting particles, making them heavier and therefore falling to the floor or the nearest surface. Once on the ground they can be removed during household cleaning tasks. Be especially careful with this, as they may end up on your bed or other furniture when they fall on the nearest surface. It is best to vacuum, as if you sweep up, these particles can become airborne again.

Ozonators: These devices clean the air by creating and releasing small amounts of ozone which destroys mould and completely eliminates unpleasant odours. However, you should be aware that ozone can be highly detrimental to you and your family's health as it can affect your lung capacity. In some cases, it is recommended to use this device as a treatment or on a temporary basis, so you will have to leave the room or your home during its operation.

HEPA Ionisers Ozonisers
Eliminates 99.97% of HEPA particles For medium spaces or rooms Ionisers Generates ozone gas Ozonisers
Zero emission of HEPA substances Does not use any type of chemical Ionisers Does not use any type of chemical Ozonisers
Can have a range of up to 70 square metres HEPA Low energy consumption Ionisers Disinfects without leaving any type of residue Ozonisers

There are other types such as ultraviolet light air purifiers, although the latter are not as popular as the 3 above.

How much do air purifiers cost?

As with any other product, prices can vary. Value for money air purifiers range from 4,000 to 10,000 MXN. However, you can find them for as much as 35,000 MXN, depending on what you are willing to spend.

Buying criteria

As you may have noticed in this article, there are several types of air purifiers or ways to clean the air, each with a different operation and characteristics. For this reason, we would like to mention the main factors that you should take into account for your final purchase:

Filters

Normally there are several types of filter incorporated into a purifier, which can be:

Electrostatic filter: mainly responsible for trapping larger particles such as hair.

Activated carbon filter: This filter is made of porous material and is ideal for removing odours as it works by combating gaseous pollutants, but does not retain allergens or other types of particles.

G4 filter: This filter consists of a fine mesh that traps finer dusts and even dust mites, and is effective at removing medium-sized particles.

HEPA filter: Finally, the most important filter in an air purifier, which, as we have already mentioned, works by trapping bacteria, germs, and significantly reduces the formation of mould in the environment. By means of an ultra-thin mesh of fibreglass threads, it eliminates and purifies the environment in various ways such as colliding in the mesh; being trapped in the mesh and colliding with other previously trapped particles.

You can find different purifiers with different designs and particular features, but in the end, their function is the same in all of them, and naturally it is to purify the air of toxic particles and pollution that may be in your home.

Scope and power

Air purifiers are generally designed to cover medium to large areas, with a range of up to 70 square metres, so they work perfectly well in the home. As mentioned above, there are also some smaller, less expensive purifiers with a more limited range.

Noise level

Many people think that these air purifiers, because of the functions they perform and the way they work, are noisy, but now with the technological advances, we find almost silent purifiers, being able to leave them running even at bedtime. We consider that a silent purifier reaches 0 to 40 Decibels.

Built-in functions

The additional functions built into the purifiers will depend on the range to which they belong. Those in the mid-range will generally ensure that they have, in addition to the HEPA filter, an activated carbon filter, which is effective against odours. Within the mid-high and high range, we can even find purifiers with an ionising and/or ozonising function included, which could be the equivalent of having 3 devices in one.
